the Middle East, SE Asia, and New Zealand. He has been associated
with bridge scour research and design in New Zealand since 1972,
having published over 40 conference and journal papers related
to bridge scour. He was recently part of a team that prepared
a strategic plan for future bridge scour research in the U.S.A,
sponsored by the U.S. Transportation Research Board, and is an

His research interests are focused on various aspects of fluvial
sediment transport including bridge scour.

Stephen E. Coleman received his
Ph.D. degree from The University of Auckland, New Zealand, in
1992, winning the Lorenz G. Straub Award from The University
of Minnesota, U.S.A, for his Ph.D. research on river mechanics.
He then worked as a consulting engineer before returning to an
academic position at The University of Auckland. His field of
expertise is in research and design relating to various aspects
of river mechanics and bridge scour. He has published numerous
conference and journal papers related to scour.
